lets start with the basics
We know one of the places mobilesafari keeps its cookies is in:
/private/var/root/Library/Cookies/Cookies.plist

We know one of the places mobilesafari keeps its history is in:
/private/var/mobile/Library/Safari/History.plist

We know one of the places mobilesafari keeps its cache is is:
/private/var/mobile/Library/Caches/Safari

We know when we clear cache/cookies/history it also clears:
/private/var/mobile/Library/Safari/SuspendState.plist

so we can all easily script deleting those files. But I'd like to identify if there are other files that are deleted as well. Wish I had a similar tool to filemon to execute here...
